If Free calculators and unit converters for general and everyday use. I wrote the codes for these calculators using Javascript, a client-side scripting language. Now we know that: a = 6. The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. As an example, given that a=2, b=3, and c=4, the median ma can be calculated as follows: The inradius is the radius of the largest circle that will fit inside the given polygon, in this case, a triangle. Given the size of 2 angles and the size of the side that is in between those 2 angles you can calculate the sizes of the remaining 1 angle and 2 sides. Given theorem values calculate angles A, B, C, sides a, b, c, area K, perimeter P, semi-perimeter s, radius of inscribed circle r, and radius of circumscribed circle R. Refer to the figure provided below for clarification. [1], sin(A) < a/c, there are two possible triangles, solve for the 2 possible values of the 3rd side b = c*cos(A) ± √[ a2 - c2 sin2 (A) ][1], for each set of solutions, use The Law of Cosines to solve for each of the other two angles, sin(A) = a/c, there is one possible triangle, use The Law of Sines to solve for an angle, C, use the Sum of Angles Rule to find the other angle, B, use The Law of Sines to solve for the last side, b, sin(A) > a/c, there are no possible triangles. All rights reserved. A right triangle can, however, have its two non-hypotenuse sides be equal in length. From Given the size of 2 angles and 1 side opposite one of the given angles, you can calculate the sizes of the remaining 1 angle and 2 sides.

It is not possible for a triangle to have more than one vertex with internal angle greater than or equal to 90°, or it would no longer be a triangle. When none of the sides of a triangle have equal lengths, it is referred to as scalene, as depicted below. Example. Area = a*b/2, where a is height and b is base of the right triangle. As can be seen from the triangles above, the length and internal angles of a triangle are directly related, so it makes sense that an equilateral triangle has three equal internal angles, and three equal length sides.

Glory to God in the highest; and on earth, peace to people on whom His favor rests! These topics are covered in my Videos on Geometry Transformations. Rotating a Triangle Around the Origin . Congruent triangles have the same size and shape. A vertex is a point where two or more curves, lines, or edges meet; in the case of a triangle, the three vertices are joined by three line segments called edges. A = angle A Given the lengths of all three sides of any triangle, each angle can be calculated using the following equation.
In a triangle, the inradius can be determined by constructing two angle bisectors to determine the incenter of the triangle. However, it does require that the lengths of the three sides are known.
